The present invention relates to new and usetul improvements in tirechaintools and has for its primary object to provide, in a manner ashereinafter set forth, a device of this character through the medium ofwhich the application of skid chains to a tire, particularly those ofthe so-called emergency type, will be greatly simplifled and expedited.V I

Another very important object of the invention is to provide a tirechain tool of theaforementioned character embodying novel means forfirmly securing thereto the usual strap of the chain.

Other objects of the invention are to provide a tire chain tool ofthe'character described which will be comparatively simple inconstruction, strong, durable, highly eflicient and reliable in I use,compact, light in weight, and which may be ance with the presentinvention.

' Figure 2 is a detail view in elevation the clamp portion of thedevice. V Figure 3 is a verticalsectional'view through the clamp, takensubstantially on the line 3-3 of Fig. 2.

Figure 4 is a view in horizontal section, taken substantially on theline 4-4 oi. Fig. 1.

Referring now tothe drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises aresilient metal strip 4 of strap metal. On one end of the metal strip, Iis aclamp which is designated generally by the reference numeral 2. Theclamp 2 comprises a jaw 3 formed as an integralpart of silient Jaw 4which is riveted at 5 to the strip I.

Coacting with the Jaw 3 is a re-.

and, further, that the slide 9 is long enough to be slipped on the freeend portion of said strap 6 which is secured between said jaws 3 and 4.Thus, the strap 6 is positively retained against lateral movement in theclamp 2. At its other end, the metal. strip I is provided with means II)for pulling said strip. This means III for pulling the metal strip I isof such size that it will not pass through the opening II in the wheelI2. The reference numeral I3'designates a pneumatic tire on the wheelI2.

It is thought that the manner in which the device is used will bereadily apparent from a consideration of the foregoing. Briefly, theresilient strip I, with the clamp 2 forward, is in,- serted through theopening II in the wheel I2. As the strip I is thus threaded through theopening I I the clamp 2 passes upwardly, and then back across the tirel3 where the strap 6 may be conveniently attached. The ring In preventsthe device Irom passing'all the way ,throughthe opening I I in the wheelI2. he free end portion of .the strap 8 is inserted thelclamp 2 and theelongated slide 9 is slipped downwardly thereover in a manner to closeand secure the Jaws 3 and 4 on said strap. Then, through the medium ofthe ring II, thestrip I is pulled back through the opening II forpulling the strap 6 therethrough. The device makes for quick appliestionof thechain and renders it unnecessary for a person to lie on the flooror ground thereby soiling the clothes.

It is believed that the many advantages of a tire chain tool constructedin accordance with the present invention will be readily understood 7and although a preterred embodiment of the device is as illustrated and.described, it is to'be under tood that changes in the details ofconstruction and in the combination'and arrangement 01' parts may beresorted to which will fall within the scope of the invention asclaimed.

What is claimed is: A tire chain tool comprising a resilient metalstrip, and a clamp on one end of the metal strip The Jaws 3 and 4areadapted to receive therebetween the tree end portion or the usualstrap 3 of. a skid chain I. Teeth or prongs 3 are pressed inwardly onthe free end portions of the jaws 3 and 4 for biting into the-strap i.

The Jaws 3 and 4 are closed and secured on the elongated slide 9 01'suitablemetal. Referring to Fig. 4 of the drawing, it will be observedthat the jaws 3 and '4 are of less width than the strap 3 for detachablyconnecting the strap or a skid chainthereto, said clamp including a pairor resilient jaws forthe reception of the strap therebetween, the widthoi said .iaws being less than that of the strap, and a transverselyelongated than the jaws and engageable over thestrap for. strap Gthroughthe medium or a transversely I s de operable on the jaws for closingsaid jaws, said slide being of a substantially greater width securingsaid strap againstlateral movement between the jaws.
